Welcome to Diagon Alley part 1

Harry was sleeping peacefully, wrapped in sheets far too soft for someone who used to sleep under stairs. The early sunlight filtered through thick emerald curtains, casting a soft glow across the marble floor. He mumbled something about "no more owls, please" and rolled over.

Compared to Tristan's apartment bed, this one felt enchanted—probably because it was. Hydra House elves had tended to everything: bed, meals, laundry. Rosa had explained the difference too.

Elves, the free ones, looked like beings out of fantasy—tall, elegant, blond, pointed ears and full of attitude.

House Elves on the other hand… well, Harry still wasn't sure what their deal was. All he'd gathered was that the Elves considered House Elves a disgrace, and the House Elves didn't care as long as the tea was served on time.

As Harry opened his eyes slowly, still in that half-asleep dream state, he found a pair of large blue eyes staring directly at him.

He screamed.

Well—it was more of a "manly yelp of surprise," if you asked him.

"Morning, sunshine," Theo grinned from about two inches away from his face, completely unbothered by the scream.

Harry sat up like he'd been hit by a Stunning Spell. "Theo! What the bloody hell are you doing in my room?!"

Theo casually plopped down at the foot of Harry's bed, smirking. "Just pleased to see the mighty Lord Hydra sleeping in like a lazy Puffskein. Honestly, it's 9:10 in the morning. You've already missed the breakfast duel."

Harry blinked. "The what now?"

But before he could say more, he noticed someone else in the room. A boy about their age, casually leaning against the bookshelf like he'd been born to look effortlessly cool. Dark-skinned, black hair trimmed neatly, wearing a clean button-up and shorts with a small House Naga pin on his chest. The kind of boy who looked like he listened to jazz, read strategy books, and insulted people politely.

[Insert image of Blaise Zabini here]

The boy gave Harry a nod. "Zabini. Blaise Zabini. House of Naga."

Harry scrambled a bit, still trying to make his bed hair behave. "Uh, nice to meet you, Zabini."

Rosa and Tristan's voices echoed in his head—

"Never call someone by their first name unless they offer it."

"Slytherin Clan tradition. Old blood etiquette. Especially for formal families."

Blaise raised a brow, approving. "You're learning fast. You might survive."

Harry gave a half-smile. "Thanks… I think."

Theo clapped his hands. "Right! Now that the Lord of Sleeping Serpents is awake, we can finally go to Diagon Alley."

Harry blinked. "Wait, we're going now?"

Blaise smirked. "Yes. And you're meeting the rest of the pit—sorry, I mean the honorable youths of the Slytherin Clan."

Theo: "Crabbe, Goyle, Pansy, Millicent, Daphne, Draco... and whoever else decides to make this morning chaotic."

Harry stared at them. "…I'm gonna need more breakfast."

Harry looked between Theo and Blaise, still half-covered in his blanket like a confused cat being told it's royalty.

"I guess you two can wait while I wash myself," he muttered, already dreading what 'wizard hygiene' entailed.

Blaise gave a smooth nod, already walking toward the door like a noble retreating from battle.

"Very well then, Lord Potter. I hope your duties are... swift and dignified."

He exited with the grace of someone auditioning for 'Most Elegant 11-Year-Old Alive.'

Harry blinked at the closing door, then turned to Theo.

"Okay, is it just me, or is he way too formal with me?"

Theo flopped back into the nearest armchair, arms crossed, like someone about to give an important lecture.

"He has to be. You're a Lord now—head of House Hydra, one of the Major Houses. Blaise isn't even a Heir; he's just a member of House Naga."

Harry groaned. "So… this is my life now? People bowing and using titles?"

Theo grinned. "Yup. At least until you mess up in public. Then they'll stop bowing and start whispering."

Harry sighed, dragging himself off the bed.

"Great. Can't wait to accidentally declare war by picking the wrong fork at breakfast."

Theo laughed. "Honestly? That has happened before. Twice."

As the door closed behind Blaise and Theo, Harry yawned, stretched—and froze when he turned and finally noticed the bathroom.

Correction: the cathedral of wizard cleanliness.

Polished marble floors shimmered with a subtle sheen. The walls were lined with pale emerald tiles, glowing faintly with runes that pulsed like they were breathing. A golden bathtub—no, cauldron-sized bathtub—sat in the middle, already steaming. Dozens of shimmering nozzles poked out of the walls like tiny hydra heads, each humming ominously.

On one end was a shower stall... floating. As in, not connected to the ground. On the other, a mirror hovered in the air like a judge waiting to deliver a verdict.

Two Elves appeared behind Harry with a pop, startling him.

"Lord Potter, your cleansing chamber is prepared," one of the Elves said formally, gesturing to the chaos ahead like it was the most normal thing in the world.

The House Elf, smaller and wearing a tea towel with the Hydra crest, added cheerfully, "Please enter. The mirror has already calibrated your 'style', Master Potter."

Harry narrowed his eyes. "My style?"

Before anyone could answer, the mirror lit up and spoke in a deep, judging voice.

Mirror: "Hmm. Messy hair. Dark circles. Classic protagonist look. Styling recommendations: 'traumatized but heroic.'"

Harry: "...Excuse me?"

The Elves didn't even blink.

The tub's golden faucets suddenly spoke too.

Bathtub: "Would Lord Potter prefer dragon-scale exfoliation or mermaid-lotion soak?"

Harry turned to the Elves, deadpan. "What happened to just… soap?"

The Elves exchanged looks.

"Primitive concept," said the tall Elf solemnly.

The shower behind him suddenly activated—water spiraling midair like a graceful dance—and something that looked suspiciously like a rubber duck flew across the room, hit the wall, then floated calmly back into place.

Harry blinked. "…Okay. You're going to have to help me. A lot."

The House Elf clapped happily. "Very good, Master Potter! We shall begin with Step One: Hair-taming incantations!"

A wand-shaped comb levitated ominously from a nearby drawer.

Harry took a deep breath, looked at the ceiling, and muttered, "Please let this be less terrifying than flying owls into magical barriers."

The mirror answered.

"Statistically, it won't be."

Next came the Tooh Brush and Toothpaste

Harry watched as the toothbrush floated up to him with military precision, hovering in front of his mouth like it was preparing for battle. The toothpaste spun mid-air, popped its cap, and squeezed itself out onto the brush in a perfect swirl.

Harry blinked, still holding nothing.

"So… do I just—?"

Before he could finish, the toothbrush zoomed forward and began brushing on its own.

"Mmfp?!"

The House Elf nodded proudly. "Fully enchanted. Brushing efficiency increased by 120%, plaque resistance spells included. We also added mint from the Forbidden Forest for that ancient bite burn."

The toothbrush kept scrubbing as Harry's eyes watered slightly. It was strong. Too strong.

"Is it supposed to feel like it's sanding my gums?!"

The Elves blinked.

The taller Elf answered casually, "That means it's working, Lord Potter."

After a minute of magical dental warfare, the toothbrush floated back and rinsed itself mid-air with a splash of hovering water, then vanished into its cubby.

Harry took a breath. "I feel like I just got punched in the mouth by peppermint."

The House Elf beamed. "Success!"

Then came the hair-drying stage.

A floating towel appeared, fluffed itself, and began dabbing Harry's hair. Another towel wrapped around his shoulders. A third tried to groom his hair like it was taming a lion.

After five whole minutes of struggling, huffing, and muttering elf-language curses, all three towels floated away in defeat.

The Elves sighed as the tall one muttered, "It is said in the old records… 'Some hair is not meant to be tamed.'"

Harry raised an eyebrow. "You have a prophecy about that?"

They nodded, absolutely serious.

"Chapter 7, Volume 3: The Untameable Hair of He Who is Chosen."

Harry was 80% sure they were joking.

...He hoped they were joking.

As he pulled on his robe and finally walked toward the exit of the bathroom, steam rolling out behind him like a warrior returning from battle, Theo peeked into the room and spoke.

"Everything go well, Lord Potter?"

Harry looked at him with the dead eyes of someone who had survived a magical spa war.

"I'm never underestimating wizard hygiene again."

Theo snorted. "Wait until you see enchanted cologne bottles. One of them chased Blaise around a hallway."

After breakfast—which was easily the best meal Harry had eaten in his life, complete with floating trays, animated cutlery, and bread that buttered itself with unnecessary flair—he leaned back, patting his full stomach.

Across the table, Blaise was chatting with Tristan like they'd known each other for years. Something about broom models, Quidditch, and who cheated the most in the Slytherin Rating Games.

Harry blinked and tilted his head. Then, curiosity struck.

"Hey, Tristan," he asked mid-sip of pumpkin juice, "why aren't you busy doing cop stuff? I figured Rosa would be the one taking us."

Tristan paused mid-chuckle at something Blaise had said and looked at Harry.

"Ah, that." He scratched the back of his head. "See, Rosa's the Head of her own House. Means she can only accompany her own child to public group events like this. It's a rule thing. Keeps the clan politics in check."

Harry blinked. "Oh… makes sense, I guess."

Tristan smirked. "So she's with Daphne today. As for me—I'm your guardian. Plus, I took the day off."

Harry blinked. "You can do that?"

Tristan snorted. "I'm a Slytherin cop. I don't ask for days off. I inform people."

Blaise raised a brow. "So Rosa's not allowed to guide me either, huh?"

Tristan nodded. "Nope. Each kid gets a parent, older sibling, or guardian. And a pair of Elves. Last time someone tried to take all the kids on their own…"

Harry leaned forward. "What happened?"

Tristan's expression went very still. Blaise dramatically whispered:

"The fire of the 12th Century Shopping District."

Harry's face paled. "Wait. That was real?"

Tristan nodded solemnly. "History books don't talk about it. Not because of secrecy. Just… shame."

Blaise whispered again. "Three buildings exploded. Someone unleashed a prank dragon. And someone else accidentally put a duplication curse on a dungbomb."

Harry blinked. "...How many kids were there?"

"Twenty."

Harry's jaw dropped. "TWENTY?!"

Tristan casually sipped his tea. "And only one adult. Poor guy aged forty years in a single afternoon."

Harry slumped back in his chair. "Okay yeah. I'm okay with this system."

Just then, the House Elf returned holding a neatly folded set of robes for the trip.

The Elf bowed, "Master Potter, your travel attire is ready. Please note the cloak is weather-enchanted and hex-resistant."

Harry blinked. "Hex-resistant?"

The Elf nodded. "Yes. Shopping can be… competitive."

Harry looked at Theo and Blaise. "What about you two?"

Theo crossed his arms with a shrug. "My older brother. He's technically the heir of House Apophis, since my father is still the Head. So he gets to babysit me today."

Harry blinked. "Is he… uh, nice?"

Theo raised a brow. "Depends. Do you consider a guy who trains by cursing trees in half for fun nice?"

Harry's eyes widened. "...No?"

Theo smirked. "Then no, not nice."

Blaise then spoke up smoothly. "My mum."

Harry blinked. "Wait, you have your mom escorting you?"

Blaise shrugged casually, sipping his tea like an aristocrat. "Yes. She's… how do I put this… intimidating."

Theo leaned in and whispered, "She's been married seven times. All wizards. All rich. All mysteriously dead."

Harry slowly turned to look at Blaise. "And you're just… okay with that?"

Blaise gave a small smirk. "They were idiots. I warned them."

Harry just stared at him.

Theo patted Harry on the back. "Don't worry. You'll get used to Blaise's… vibe."

Just then, one of the Elves popped into the room again with a respectful bow.

"Master Potter. Your transport group is ready. Lord Tristan and the other Slytherin heirs will be gathering in the front courtyard."

Harry sighed as he stood up, dusting off his perfectly-fitting cloak. "Alright… time to face the snake pit."

Theo grinned. "That's the spirit."

Blaise casually added, "Don't worry, you'll either make friends… or rivals. Either way, it'll be fun."

Harry blinked. "...That's not comforting at all."

They all laughed as they left the dining hall—headed straight into the chaos that was the future of Slytherin.

Harry made his way to the courtyard, As he got out, he was shocked.

Harry saw a Small Army of Kids, some pairs of Siblings, and some twins, others one, some of them seemed to be chatting, they weren't, as they also looked at each other, house rivals were already there.

Harry saw maybe 100 or more kids, as he looked at Theo. "Ok, I know there's like 13 Houses, but um this many kids".

Theo smirked looking at him. "Not all of them are from the House, some are from the mountains"

Harry looked at the Mountains in the Slytherin Clan as he spoke. "Right, the mountains are a place where the Families that aren't part of the 13 Houses live".

Blaise looked at Harry as he spoke. "Lord Potter, will you find does kid wearing grey, now if you don't mind"

He and Theo walked up to their Respective House Groups as they knew, Flags, Harry looked around as he found Tristan holding a Hydra Flag.

As he walked up to him, as he came next to Tristan, everyone stopped, all the kids from different houses looked at him. Harry gulped as he looked at him

As Harry stood next to Tristan, the silence in the courtyard was deafening.

Dozens of eyes were on him—some curious, some wary, a few impressed… and more than a few carrying the look of predators sizing up fresh meat.

Harry forced a smile. "Sooo… are they all staring at me, or do I have something on my face?"

Tristan leaned in, whispering, "No, no. They're just trying to figure out how someone their age became a Head of House. It's basically like a lion cub walking into a den of snakes and declaring, 'I own the place now.'"

Harry muttered. "Great. Thanks for the confidence boost."

Tristan chuckled, clapping him on the back. "You'll be fine, just don't trip."

From the crowd, House banners fluttered in the wind—green serpents, coiled dragons, twin-headed vipers, and even banners with shimmering illusion spells woven into the fabric. Each house had its own unique magic signature embedded in the sigil.

Then came her.

In the Amphisbaena group, near Rosa, a girl stepped forward. Hair golden and curled into perfectly styled twin tails, she had the refined posture of nobility and the eyes of someone trained to take control of a room.

Her gaze locked on Harry with mild curiosity. Not admiration. Not scorn. Just calm, calculating interest.

Daphne Greengrass.

[Insert image of Daphne]

She leaned closer to her mother. "So, he's the Hydra head?"

Rosa nodded, keeping her own tone neutral. "Yes. He's young, new… but he's carrying the bloodline that vanished for nearly a millennium. Respect him."

Daphne flicked her twin tails with a soft huff, the anime energy practically glowing around her. "Very well. But if he's a disappointment, I'm not pretending to be impressed."

From another group, a darker-haired boy with pointed features—leaning half-lazily against the Mamba banner—scoffed.

"You'd think being the 'Boy Who Lived' would make him taller."

Pansy Parkinson snickered beside him, hiding her laughter behind a silk fan enchanted to blow glitter. "He is cute in a scruffy kind of way though. Like a stray Kneazle."

[Insert image of Pansy]

Harry blinked and whispered to Tristan. "Do I say hi? Or do I just… nod and hope they don't kill me?"

Tristan sighed. "You do the third thing. Pretend you're confident and pray no one smells fear."

Just then, from behind the Python house banner, he appeared.

Blond hair slicked perfectly back, robes perfectly pressed, an aura of smugness so thick it could drown a hippogriff.

Draco Malfoy.

[Inser image of Draco Malfoy]

He strutted toward Harry like he was walking a fashion runway, flanked by Crabbe and Goyle like bulky, confused bodyguards.

"Well, well… if it isn't the resurrected Hydra," Draco drawled with a smirk. "Hope your scales are tough. Clan politics aren't very kind to new blood."

Harry raised an eyebrow, unsure whether to respond with sarcasm or punch him in the nose.

Before he could choose, Tristan stepped forward with a grin. "Morning, Lord Viper. Still using your father's shampoo, I see."

Draco narrowed his eyes. "Funny. Real funny, Tristan."

Tristan turned to Harry and winked. "I can do this all day."

Before anything else could escalate, the sound of hooves clopping echoed into the courtyard.

All the kids turned as several magical carriages, drawn by what looked like crossbreeds of Thestrals and serpents, slithered and stomped their way toward the gathering.

An Elf announced, "All students ready for Diagon Alley transport—prepare to board!"

Tristan nudged Harry. "Welcome to your first day in Slytherin Society, kid. Survive it—and the rest of Hogwarts might actually be the easy part."
